I am building a BMC IMPEC (all Campagnolo). I have a Colnago M10 Super Record 11s with the Rear Dual Pivot brake option, and I am debating using the standard (single) Super Record Rear Brake on my IMPEC. I have had very good results on the M10 - great brakes - but assume the standard rear is typical great Campagnolo and should save me some weight and look kinda cool on the bike.

I do know the single is a bit tougher to center because its not a solid once mounted on the bike (has some wiggle) - but it's the rear and I have similar issues with my THM Fibula and once set well they work fine.

My vote goes to the dual pivot. When Campagnolo went to the single pivot it saved a bit of weight and the marketers decided that in lieu of hyping sheer braking power they would hype the "better modulation" aspect. I was using their dual pivots before that, then used the single pivot again until they came out with the dual pivot once again. Despite the marketing line, I feel that modulation is better with the dual pivot. Why? Because it simply operates more smoothly and evenly. Modulation comes primarily from the rider and the smoothness of brake operation. The dual pivot is easier to, and stays centered better than the single pivot as well. And it is buttery smooth in operation. These things are more important to me than a few grams.

I just installed the single. Have both sets - removed the dual from my CA to install the Fibula. The single does wiggle - one spring - but I think it should center ok. The dual is locked and never moves which is nice - but I like the look of the different brake in the back. Brake is "prettier". Has anyone done or seen 2 singles. That would have been a cool option for my lightweight CA instead of the Fibula maybe.

But if like me when some new latest groupset comes along you buy install on your best bike, then move that older hardware down the bikes over years I've found the dual pivot just keep on working. record ones from 2004 or 2005 on my old winter bike work like new
